Series/Type: B82790
Date: December 2006
Data Sheet
© EPCOS AG 2006. Reproduction, publication and dissemination of this data sheet and the information contained therein without EPCOS’ prior express consent is prohibited.
Double chokes
Rated voltage 42/80 V AC/DC
Rated current 200 to 1000 mA
Rated inductance 5 NH to 4.7 mH
Construction
■ Current-compensated ring core choke with ferrite core
■ Bifilar winding (B82790C0*)
■ Sector winding (B82790S0*)
Features
■ Case flame-retardant as per UL 94 V-0
■ Suitable for reflow soldering
Special types for conductive adhesion
and ambient temperatures up to 150°C on request
Applications
B82790C0*/S0*N2Chokes for data and signal lines
■ B82790C0*:
Suppression of asymmetrical interference coupled in on lines,
whereas data signals up to some MHz can pass unaffectedly
■ B82790S0*:
Suppression of asymmetrical and symmetrical interference
coupled in on lines. The high-frequency portions of the symmetrical
data signal are decreased so far that EMC problems can be
significantly reduced.
Terminals
■ Lead-free tinned
